CDC may enter into an agreement with an individual, upon such terms as the CDC considers to be reasonably necessary, indicating that the individual consents to any of the public health measures authorized under this part, including quarantine, isolation, conditional release, medical examination, hospitalization, vaccination, and treatment: provided that the individual’s consent shall not be considered as a prerequisite to any exercise of any authority under this part.

…individuals who violate the terms of the agreement or the terms of the Federal order for quarantine, isolation, or conditional release (even if no agreement is in place between the individual and the government), he or she may be subject to criminal penalties.
